I'll create a comprehensive scientific calculator with all the essential mathematical functions and operations.

I've created a comprehensive scientific calculator with the following features:

Key Features:

Basic Operations:

• Addition, subtraction, multiplication, division
• Decimal point input and negative numbers
• Clear (C), Clear Entry (CE), and Backspace functions

Scientific Functions:

• Trigonometric functions (sin, cos, tan) with RAD/DEG mode toggle
• Logarithmic functions (log, ln)
• Power functions (x², x³, x^y, √x)
• Mathematical constants (π, e)
• Factorial (x!) and reciprocal (1/x)

Memory Functions:

• Memory Clear (MC), Memory Recall (MR)
• Memory Add (M+), Memory Subtract (M-)
• Memory indicator in the display

Advanced Features:

• Angle mode toggle (Radians/Degrees)
• Error handling for invalid operations
• Responsive grid layout optimized for touch interaction
• Dark theme with color-coded button categories

Button Color Coding:

• Gray: Numbers and basic functions
• Orange: Basic arithmetic operations
• Blue: Trigonometric and logarithmic functions
• Green: Power and root functions
• Red: Clear functions

The calculator handles edge cases like division by zero, domain errors for logarithms of negative numbers, and factorial limits. The display shows the current angle mode (RAD/DEG) and memory status (M) when applicable.

Perfect! I've updated the calculator to have a white background with appropriate color adjustments:

Changes Made:

• Card background: Changed from dark gray to white with a border
• Display area: Changed from black to light gray with a border for better contrast
• Text colors: Updated to dark colors for readability on white background
• Button colors: Adjusted all button colors to work well with the white theme while maintaining the color-coding system

The calculator now has a clean, light theme while preserving all functionality and the intuitive color-coding for different button categories.
